AB - The radial tilt between vertical direction of disc and optical axis of lens in standard DVD traverse, plane vibration and warp of disc are important parameters in production and detection of DVD discs. In this paper, a new dynamic detection method which we call pulse-width method is proposed to detect the radial tilt, plane vibration and warp through analyzing the optical and electrical features of traverse. Based on the method, an apparatus is developed and the experimental results compared with the analysis results verify the validity of the method. The applicability and testing precision are also analyzed.
